Frame for a floor drain

Abstract

A frame (4) is designed to be inserted into a channel body (3) of a floor drain (1), the channel body forming an outflow channel (8) and having an outflow opening (9). The frame includes at least substantially vertically extending side walls (11) arranged in the form of a frame and which together form a receiving opening (12). An at least substantially horizontally extending frame flange (13) adjoins the upper edges of the side walls (11) and surrounds the receiving opening (12) in a frame-like manner. Projections (14) projecting into the receiving opening (12) are provided on opposite side walls (11) and form a receiving framework to receive and support a cover (5) to be inserted into the frame (4) from above, characterized in that the projections (14) are provided in the form of indentations.

I claim: 
     
       1. A frame ( 4 ) made of sheet metal and designed to be inserted into a channel body ( 3 ) of a floor drain ( 1 ), said channel body forming an outflow channel ( 8 ) and having an outflow opening ( 9 ), said frame comprising at least substantially vertically extending side walls ( 11 ) arranged in the form of a frame and which together form a receiving opening ( 12 ), and an at least substantially horizontally extending frame flange ( 13 ) that adjoins the upper edges of the side walls ( 11 ) and surrounds the receiving opening ( 12 ) in a frame-like manner, wherein projections ( 14 ) projecting into the receiving opening ( 12 ) are provided on opposite side walls ( 11 ) and form a receiving framework to receive and support a cover ( 5 ) to be inserted into the frame ( 4 ) from above, characterized in that the projections ( 14 ) are provided in the form of indentations. 
     
     
       2. The frame ( 4 ) according to  claim 1 , wherein the upwardly facing surfaces of the projections ( 14 ) extend at least substantially horizontally. 
     
     
       3. The frame ( 4 ) according to  claim 1 , wherein the projections ( 14 ) are of elongate design. 
     
     
       4. The frame ( 4 ) according to  claim 1 , wherein the lower edges of the side walls ( 11 ) extend in a straight line. 
     
     
       5. The frame ( 4 ) of  claim 4 , wherein the floor drain ( 1 ) has a channel body ( 3 ) which forms an outflow channel ( 8 ) and has an outflow opening ( 9 ); a frame ( 4 ) which can be inserted into the channel body ( 3 ) from above; and further comprising a cover ( 5 ) which can be inserted into the frame ( 4 ) from above, wherein the dimensions of the frame ( 4 ) and the cover ( 5 ) are matched to one another such that the projections ( 14 ) of the frame ( 4 ) receive the cover ( 5 ) inserted into the frame ( 4 ). 
     
     
       6. The frame ( 4 ) of  claim 1 , wherein an area of the side walls  11  surrounding the projections  14  is devoid of openings or through-holes. 
     
     
       7. The frame ( 4 ) of  claim 6 , wherein the frame is formed as an integral, unitary piece of material. 
     
     
       8. The frame ( 4 ) of  claim 6 , wherein the projections form receiving cavities configured to receive thin-bed mortar therein during installation of the frame.
